I have 1 of the above televisions. It suddenly decided to show no picture from any input. It has been in for repair here locally and a fault has been identified. This was on the Inverter Board and concerned a Tx. marked 6024B709005 (GP) -03. The technician has removed this part but was unable to source a replacement. Does anyone know where I can obtain one please.
Cheers,
Mac

Below are Top & Bottom views of the offending item, pardon the hair.

The transformer looks open circuit. The break seems to be the bottom left clearly seen between the winding and the edge connector. Careful cleaning and soldering a bridging wire will cure it.

Thanks for that Theo,
I got all excited and thought "I can do that", but twas not to be. It looks like it due to my poor photography, lighting etc., but on closer examination with a strong magnifier it seems that the wire does actually continue into a gel-filled cavity, presumable connected within.

hi
have you measured the windings with meter to check the
readings (ohms)

[Mac0001UK]

Hi Sparky,
I haven't mainly because I would have no idea which pins to measure across. If you have any clues on that I would be most grateful to receive them.
To be quite honest I have no idea what this component actually is. To me it looks like a SOIC plugged into the top of some sort of winding assembly but I am probably very wrong.
Anyway, any help would be most gratefully received.
Cheers,
Mac

Hi Sparky Again,
I have now put a meter across the pins. All show as open-circuit except between 2 & 3 which are virtual s/c. I can physically see the wires from each end of the centre windings terminating there so that makes sense. Where the other windings actually terminate is anyones guess. I still have to consider that it is the component on top of the windings at fault.
Cheers,
Mac

hi
the component on top is just ferritte cover ,it
stops the coils from vibrating i will look in workshop
for part you require

Sparky,
Thank you very much, I look forward to your reply.

hi
have had a look not got one
can you read pin 4 + 5=
read 1+8=
pins2+3 do read s/c
thanks sparky

Hi Sparky,
Thanks for taking the time and trouble to look for me.
I have measured across 4+5 = open circuit
I have measured across 1+8 = open circuit

I don't know.

I have done web searches using the Part Number on the top but no joy &, you wouldn't believe it, the standby telly I was viewing has just gone totally dead as well!  :mad:

Cheers,
Mac

[sparky]

sorry can't help you for replacement
will keep my eye's open in case i come
across one

[Mac0001UK]

Thanks very much Sparky,
I live in hope and down to my last rather inadequate telly for the moment.  :huh1:
Chers,
Mac

Both windings are O/C. They should each read between 950 and 1000 ohms. Pins 2+3 should read S/C or if you have a good meter 0.5 ohm. Check the board to see if it was made by DARFON, if so the part you need is available under another number. 4006 or 9?????????????????? Seen them on ebay.

[sparky]

beware they say will work but don't you might not get your
cash back,check previous posting

[theo laird]

Tend to agree, there are plonkers out there selling the o/c ones.

Thanks Theo,
I shall have a look at the board, and be careful where I go from there.
Cheers,
